Ronian's latest paper has been published in the European Journal of Physics! In this new work, Ronian extends conventional optical radiometry to the case of non-stigmatic, non-aplanatic, and non-isoplanatic lenses. Click HERE to read the open-access author-accepted preprint!
Ronian will be giving an invited talk at the 2021 Frontiers in Optics and Photonics Symposium organized by the Indian Institute of Technology Delhi! Click HERE to download the slides!
Wrapping up the year in 2020, Ronian publishes a technical note describing how to apply a simple formula to compute the relative illumination of an un-vignetted imaging lens system in terms of image distortion, differential distortion, chief ray angle (in object space), and the size and shape of the entrance pupil.
Ronian publishes a white paper describing an extension of his earlier work on an optical design technique performed through sequential ray tracing to achieve uniform top hat illumination for extended sources (such as high-powered array LEDs) using only spherical lenses.
